Hi Matt, Good day, If you would like to file a feature request , you may do so by submitting it in http://www.vmware.com/company/contact/contactus.html?department=prod_request . Its a simple questionaire and will get routed to the appropriate teams for further review. The same link is available in every KB article under section "Request a Product Feature". .

Hi Michael, 1- During provisioning the host attempts to keep files contiguous, but it truly depends on the how fragmented the volumes are. As you can imagine a SVMotion of a vmdk will punch a hole in the middle of a volume and host has re-use the space. So answer is "it depends", it may or may not be contiguous. vmkfstools will display multiple ranges if its non-contiguous. 2-As long as the vmdk files are not locked(VM powered on) , this should work.

Michael, As indicated earlier this is not the best approach, sharing nonetheless since you have requested Do note that VMware does not support/perform data recovery services and I doubt if there are any utilities to provide file to LBA mapping. As reverse engineering , you can try these for vmdk's alone. see the below example, ~ # vmkfstools -t0 /vmfs/volumes/Openfiler_3/ Test/Test.vmdk Mapping for file /vmfs/volumes/Openfiler_3/TestDBS/Test.vmdk (1073741824 bytes in size): [           0:  1073741824] --> [VMFS Z- LVID:52d63c04-fcdad496-be74-000c29409d5c/52d63c03-c120e0bb-6715-000c29409d5c/1:(  2746220544 -->   3819962368)] Logical LBA range is for file is - [ 0:  1073741824] Physical Byte offsets - 2746220544 -->   3819962368 Divide the physical byte offset by 512 and you would have the physical HBA range. Which may or may not include the LBA's you know as impacted. Pretty much needle in a haystack!!!

Yes, that certainly is in the data region also it looks like you hardly have 1 MB of corruption- that is less than one block(if contiguous) of VMFS volume. So I can understand the pain that you do not prefer full restore/recreation But I doubt if it is possible to trace the file associated. If you are not specific about free utilities , try the vendor listed here VMware KB: Data recovery services for data not recoverable by VMware Technical Support

Hi , It is important to understand if the damage is on the metadata of the LUN or the actual data(where VM resides). Metadata spans about less than  first 1.5 GB of the vmfs volume. You would not be able to selectively replace a file into a LBA region(even if you manage to trace it I not sure if this is possible at all), the volume will be corrupted nonetheless. If its metadata or actual data, avoid powering off VM's Safe Options are 1-Use converter to migrate V2V the VM's -- I say this since in the past, Storage VMotion of VM from a corrupted datastore can lead to VM crash and subsequently may fail to power on. 2-Re-create VMFS volumes on affected lun I know this is the hard way. But certainly would not recommend replacing individual files from tape, knowing that there is some damage to the filesystem. Hope this helps and all the best.
Have a look at VMware KB: Storage vMotion to thin disk does not reclaim null blocks

AFAIK., I believe you can go as far as using hexdump to look at raw hex data associated to LBAs & perhaps take a back up using dd. But only vmfs driver can enumerate the contents/translate those into readable file. There are certain vmkfstools options to understand disk layout/geometry There is also a utility called VOMA from vSphere 5.1, if incase you are looking to check integrity of a VMFS volume If I may, Can I understand the requirement , I may be able to provide more insight or directives.

About your support experience, If incase you raised the support request off business hours(presuming this,  since this post is on a weekend), you may be contacted during business hours(weekend support has skeletal staffing and supporting production outages) otherwise you may need to escalate to get appropriate attention.
Did you run into this ? "If you use the vSphere HA Specify Failover Hosts admission control policy and designate multiple failover hosts, VM-VM affinity rules are not supported."

Are you able to login to vSphere client ? Is the inventory service running ? Also look at VMware KB: vSphere Web Client displays empty inventory

To provide a completely different perspective to this thread I would suggest you review the below two features to address your queries or concerns in the long run 1-Host Profiles 2-Auto Deploy Look at Insight into Auto Deploy that I have put together for a high level overview. This may be a giant leap to manage lifecycle of your environment but this next gen stuff. Caveats/Gotchas 1-You need PXE environment 2-Ensure hardware compatibility during upgrades

If you are running a production environment, it is a mandate to keep you environment up-to date. Bear in mind that Environment need to be free of the latest vulnerabilities. You do not want an environment prone to heartbleed Latest updates are enhanced,optimized and has several bug fixes Push the limits of virtualization, for the innovator that VMware is... amazing things are added every other day. Update manager makes these tasks fairly automated, you can orchestrate and update an entire cluster of hosts with zero downtime to your virtual machines. This does go against the traditional quote of administrators to not change anything if its working.. Well there is a significant trade off to resist change

Dan, The three services are likely to be in a stopped state, if in case you have joined the host to domain but have not restarted the host. i.e. these services are set to start or stop with the host and will take effect on reboot to start automatically(now that host is joined to domain it will kick off the services on boot). For your second query about why you need to pass credentials every time, it could be VMware KB: Logging on to an ESX/ESXi host with Windows session credentials fails Or http://kb.vmware.com/kb/2062992

If you are looking to setup & draw from an automated pool to draw the MAC address for VM's, this is not user configurable/available. This is internally maintained and provisioned when network adapters are added to VM's. This is not guaranteed from changing. in a multi- vCenter environment there could be duplicate MAC in the environment. These are based on arbitrary algorithm that vcenter uses based on an instance ID. If your application is sensitive to MAC address remaining the same in the lifecycle of the VM, (sometime is the case with legacy app licensing tied to hardware) Set it manually to static. To do this, follow the document vSphere 5.5 Documentation Center KB article VMware KB: Setting a static MAC address for a virtual NIC Abstract ===== Add these two lines to the virtual machine's configuration file: ethernet0.addressType = "static" ethernet0.address = 00:50:56:XX:YY:ZZ Where XX is a valid hex number between 00 and 3F and YY and ZZ are valid hex numbers between 00 and FF. The value for XX must not be greater than 3F in order to avoid conflict with MAC addresses that are generated by the VMware Workstation and VMware GSX Server products. Thus the maximum value for a manually generated MAC address is: ethernet0.address = 00:50:56:3F:FF:FF VMware ESX Server virtual machines do not support arbitrary MAC addresses, hence the above format must be used. As long as you choose a hex value that is unique among your hard-coded addresses, conflicts between the automatically assigned MAC addresses and the manually assigned ones should never occur. ===== Let me know if this addresses your question. Or please share a more detailed requirement/use case.
Hi Bayu, Your information is more up-to date(as on April 2014), thanks for sharing this
News is that NSX licensing may be per port, not per VM.
